This topic is an integral part of the pilot project of Ministry of Agriculture, cold, windy and sand conservation tillage , the subject aimed to develop a cold sand farming-pastoral zone tillage characteristics suitable for local use small grains till planter . According to the characteristics of farming on the cold sand areas and existing no-tillage equipment usage survey and analysis of the following characteristics : design a flat shovel opener , planting, weeding , and surface operations the equipment once into complete ; successful kinds of fertilizer bisects facilities used in the machine effectively reduce ditching depth , reduce the planter working resistance ; design the a squirrel cage repression roller with rubber bumps , flat surface at the same time , achieve the conservation tillage system on the surface repression of technical requirements , but also play the role of auxiliary weeding ; selected the sponge friction Metering box to meet the sowing quantity and sowing seeding conditions uniformity requirements ; field experiments showed that : good results sowing sowing amount and sowing uniformity meet the technical requirements of the Ministry of Agriculture till planter ; herbicidal effect , more than 90% overall in addition to sloppy reached the herbicidal effects of traditional farming ; effectively reduce the surface soil bulk density , soil bulk density of sowing before and after reduced about 20% , is conducive to the growth of crops ; work around the stubble covering no significant effect ; ground temperature has significantly improved compared with the previous no-till machine , shorten a crop germination time ; native met the design requirements , in the cool sand farming characteristics , is a strong adaptability of small grains no-tillage equipment .
